I've got a 4 foot tank with a very healthy population of Platies, but I'm looking for some others just to add a bit of variety. I had a Pearl Gourami and a Kissing Gourami, but they just weren't rough and tough enough to compete for food with the Platies. I've been looking at Angel fish, or Electric Yellow Cichlids. I'm after something that will help keep the Platy population down (heavily planted tank so will always have some babies) and keep the snail population down but I know that no fish lives on snails alone. I'm after some colour really.
